*1 PVC lining type is available for the size 32 mm to 150 mm as marked gray.

Its scale range is shown in the column Scale range 2 as marked gray.

Full-scale flow rates for the PVC lining pipe are calculated based on the

inner diameter of ESLON® ESLOCOAT LX tee fittings (Sekisui Chemical

Co., Ltd). The maximum rating is 1 MPa. If you use other fittings,

additional calibration is needed. Please check “D” and “L” in the figure at

the end of this document and the kind of pipe, and then contact us

*2 Scale ranges of 20, 25, 32 mm size for 2 MPa class are shown in the

brackets in above table.

*3 The inside diameter of main pipe of 20 to 32mm in 1MPa class is based

on the three-way socket (JIS B 2301).(The three-way socket shall be

attached upon request.)

*4 The inside diameter of main pipe of 20 to 32mm in 2 MPa class is based

on three-way socket (Sch 40). The three-way socket is supplied by

customer.

*5 The inside diameter of main pipe more than 40mm in 1 MPa class is

based on SGP (JIS G3452) Carbon steel pipe for piping, and the inside

diameter in 2 MPa class is based on the carbon steel pipe for STPG (JIS

G 3454 Sch 40) for pressure piping.
